effect of sacral erector spina plan block on total hip arthroplasty

Conditions: Postoperative Pain

Summary: total hip arthroplasty (tha) is a surgery that relieves hip joint pain and improves its functions and is widely performed in the elderly population. new analgesic methods need to be developed to protect these patients from the pain and side effects of opioids used for treatment. many scales are available to indicate postoperative patient recovery. one of these is the quality of recovery-15 (qor-15) recovery test, which was first applied by stark et al. in 2013. we think that an espb applied from the sacral region will spread to the lumbar region by diffusion, affect the lumbar plexus, and provide complete analgesia in the ventral and dorsal regions of the hip by affecting the sacral plexus in the sacral region. the investigator's primary aim in this study is to evaluate the effect of sacral erector spinae plane block (s-espb) on the quality of recovery and healing after tka through the qor-15 score and to evaluate its effect on postoperative pain.

Eligibility criteria:
inclusion criteria: * patients who will undergo unilateral tha * spinal anesthesia * 18-80-year-old patients * patients with asa i-iv * patients who will stay in the hospital for at least 24 hours exclusion criteria: * patients who do not want to give consent * patients under 18 years of age and over 80 years of age * patients for whom regional anesthesia is contraindicated * patients with confusion * patients with asa v and above * patients with abnormal bleeding profile * patients using anticoagulants * patients with infection in the area to be treated * emergency cases
